The Prisoner Juggernaut is a large, muscular monster that is seen in Silent Hill: Downpour. They appear as background characters in Oakside Park in PlayStation All-Stars Battle Royale.
In the first encounter with this monster in Overlook Penitentiary, it is seen ripping off a metal gate so that it can engage Murphy Pendleton. In addition to being encountered in standard monster fights, they can reach through cell bars to grab Murphy as he passes. They are dominant to the smaller Prisoner Minion. On one occasion, a Prison Juggernaut leads two Minions around on meat hook "leashes" like dogs.
The Juggernaut only appears in scripted encounters toward the end of the game in Overlook Penitentiary. This imposing enemy uses his devastating charge attack to get into melee range; then he follows up with a series of powerful strikes. Juggernauts also have an enormous amount of stamina, able to absorb huge amounts of damage from melee strikes and firearms alike. They also frequently ignore attacks, shrugging them off and following through with their own attacks. When facing a Juggernaut, it's best to dodge its' charge. Land a few hits while the enemy turns to face Murphy, then use basic melee tactics; block the Juggernaut's strikes and counterattack when finding an opening. However, it is advised that the player use firearms or flee.
